GLASSWARE.

Specification of Letters Patent.

Patented May 19, 1914.

Application filed July 1, 1909. Serial No. 505,437.

To all whom it may concern Be it known that I, OTIs A. MYGAT'I, a citizen of the United 'States, residing at New York, in the county of New York and State of New York, have invented certain new and-useful Improvements in Glassware.

The object of my invention is to furnish glass bodies with ornamentation, so that the designs formed on the surface will produce sparkling effects like that of the diamond and other brilliants.

According to my invention one surface of the glass body is provided with protuberances similar to the top portion of the diamond and other brilliants, while on the other surface a backing is provided which has a similar effect to that produced by the bottom portion, or culasse, of brilliants.

Figure 1. is a cross section of a glass body,

embodying my invention, the protuberances being shown in elevatlon. Flg. 2. 1s a cross section through a series of the protuberances.

Fig. 3. is a perspective view from below of a globe or reflector for artificial lights, provided with a modification of my invention.

As shown in Figs. 1 and 2, the top portion of the glass body is provided with protuberances having facets thereon, resembling those of the top or front of the diamond. The bottom surface is covered with protuberances of the shape of the culasse,

or bottom portion of the diamond. By the use of facets disposed at suitable angles so that the light striking the various surfaces will be suitably reflected a very brilliantappearance may be obtained.

The reflector shown in Fig. 3 is provided with discontinuous, brilliant-like protuberances on its exterior surface. The ribs are preferably of the same width as the exterior protuberances. In order to produce a sparkling effect from light reflected from the I outer. surface of the reflector, the inner prisms should be of such an angle that they will be double reflecting. The ribs in this case take the place of the culasse, or back of thediamond. In the case of reflectors such as that shown in the drawing, having an open mouth, the angles of the facets on the outer protuberances may be such as to doubly reflect light coming from the inner artificial light source. On the other hand, in the case of structures intended to transmit light from an inner source, the angles In testimony whereof I ailix my signature 7 in presence of two witnesses.
